Deduplication Across Multiple Different Data Sources to Identify Common Devices

2. The system of claim 1, wherein the first set of stations and the second set of stations at least partially overlap.

3. The system of claim 1, wherein the comparison controller is to apply a restriction to first data from the first data source and second data from the second data source before the comparison controller is to identify the first device and the second device as the possible common device.

4. The system of claim 3, wherein the restriction is a geographic restriction.

9. The system of claim 8, wherein the third metric calculator is to compute a Levenshtein distance to determine the number of operations.

11. The system of claim 1, wherein the common device selector is to determine that the first device and the second device are a common device when the joint score satisfies a threshold.

12. The system of claim 11, wherein the threshold is satisfied when four times a standard deviation of the joint score is less than a mean of the joint score.

14. The system of claim 1, further including a fourth metric calculator to calculate a time distance metric based on a first set of time events of activity of the first device and a second set of time events of the second device, the comparison scorer to determine the joint score based on the time distance metric.

16. The system of claim 15, wherein the first set of stations and the second set of stations at least partially overlap.

17. The system of claim 15, wherein the means for identifying is to apply a restriction to first data from the first data source and second data from the second data source before the first device and the second device are identified as the possible common device.

18. The system of claim 17, wherein the restriction is a geographic restriction.
